Featured Ashes to Ashes, Funk to Funky...

Just pulled this ashtray out of our buffet. It belonged to an aunt, long passed away, who was a world traveller. She went to the far East ca. 1950.
I know nothing about silver hallmarks, but to me this looks like USAG or JSAG with 900 underneath it. I don't know what the top letters mean, but I think silver purity is 900.
It's about 4 1/4" U.S. wide and 3/4" tall. I'm guessing ca. 1945? It has been well-used for its intended purpose, although I'm sure a cigarette has not been in it for many decades. Still, it's pretty funky and after a thorough cleaning I don't think the center will ever really come clean.
Oh, and the band around the top features repeating indigenous types smoking, with an odd spider web appearing only once.
I have deliberately not done a search of any kind for other examples, preferring instead to rely on the expertise of my fellow boardies.

 

JS (?) is a maker and AG is likely "silver", aka 'argento'. It wouldn't surprise me if this was Peruvian or similar.

 

...We know Major Tom's a junkie
Strung out in heaven's high
Hitting an all-time low

 

I knew the next line but not the rest.

 

Maya figures, no Mexican marks, so probably Guatemala, which is known for this cut-out type of silverware.
I would have bought it in a heartbeat, and I don't even smoke.

 

very nice !!!!!!
